Fastening means for the free edges of sides 51 and 54 is provided and is shown more clearly in Figs. 3, 4 and 5. As shown in these figures, the edges of sides 51 and 54 are turned sharply inwardly to form flanges 51a and 54a and these flangesthemselves flanged as at 51?) and 545 so as to nest one in the other, thus giving broad flat meeting edges 51a and 54a and also by reason of the nesting flanges 51b and 54b edges that will align automatically.

The flanged edges of sides 51 and 54 when brought together are securely fastened by means of two or more buttons 60 operable,

independently or in tandem, as shown, througha connecting rod 61 and handle 62, these parts being carried by side 51.

Further, the cabinet is preferably provided with corner braces 65, casters 66, and means for locking it open such as the toggle 67.

As shown clearly in Figs. 1, 2, 3 and 6, when the machine is folded into the cabinet,

the ironer (and by ironer is meant the mechanism and parts used in the ironing operation) assumes a position wherein the roll. etc. are vertical, while in operating position, these are horizontal as shown in Fig. 7. The parts for accomplishing this change in position are shownclearly in Figs. 6 and 7.

In the latter figures, the platform 90 is shown as hinged to'a leg as at 71 and the leg is also hinged as at 72 to the bottom member 56 of the cabinet. Leg 70 is preferably formed of'two metal bars 70a and 70b so shaped as to have a base substantially as w de as side member 51 and to be nearly as wlde at the top as the platform 90, the two bars 70a'and 705 being diagonally braced as at 700 (see Fig. 6a).

Hinged as at 73 near the top of bars 7 0a and 701) are two extensible members 74 formed preferably of tubes 75 into which telescope rods 76 each carryingv a fixed collar 77 between which and around the rods are compression springs 7 8.! The free end of rod 76 is rounded and co-acts with a seat 79 in the under side of platform 90.

It should be noted that the upper ends of bars 70a and 705 are bent forward so that the hinge 73 is a short distance in the rear of the line between hinges 71 and 72 and when the ironer occupies the position indicated in Fig. 6, the seat 79 is almost on said line, so that, when the spring 78 is compressed as it is in Fig. 6, very little effort is require to maintain this state.

The springs 78 are rather heavy, strong aseaeee -This means is shown in Figs. 6 and 7 and consists of a toggle 8081 between a bar 82 secured to side 51 of the cabinet and bar 70?), and actuated by a spring 83 secured to a knuckle of the toggle and anchored as by lug 84 to side 52 of the cabinet. This toggle 8081 is so constructed and arranged as to be almost straight when the ironer is folded (see Fig. 6). A comparatively weak spring 83 will therefore lock the ironer in folded position against the strong springs 78. This locking means is not essential as when the ironer is folded and the cabinet closed,'the mechanism willstay in folded position without undue pressure upon the cabinet sides.

As indicated in Figs. 6 and 7, the platform is formed most conveniently in three parts bolted or otherwise secured together, the mid portion being part of a central main frame member (to be described later in detail) with the end portions 92 and 93 on each side thereof. To part 92 is hinged the leg 70 which supports this end of the platform, while the other end rests upon one or more arms 94 secured to side 54 as shown in Fig. 7. Part 92 also carries on its rearward edge a roller or slide 95 co-acting with guide 96 on side 52 to assist in folding or unfolding the ironer.

In orde'r to prevent the upper portions of sides 51 and 54 hindering the ironing operation, and also to provide a longer platform for the ironer, the upper part of each side is hinged to the lower as shown in Figs. 2 and 7. Those upper parts numbered 97 and 98 respectively, lap over the lower parts far enough so that when folded down as shown in Fig. 7 they will extend inwardly of the cabinet side to the edge of the platform and form continuations thereof.

Main frame The ironing mechanism preferably consists' as is usual of an ironing shoe adapted to be heated and a padded roll operable to press the garments, orother articles to be ironed, against the shoe and move them over the smooth hot surface thereof, although with minor alterations it is possible to provide for using a roll instead of a stationary shoe and for the heating of either of these two, and J such modification is contemplated. It should also be noted that the device is not limited 101 extending laterally to form the mid portion of the platform 90, and the lateral extensions are provided with flat ends against which the platform wings 92 and 93 abut and are secured as indicated in Figs. 1, 2, 6 and 7. The arms of the U-shaped framewmemher which are hollow and are numbered 102 and 103, support respectively the ironing shoe and the roll. I

It will be noted that all of the ironing machine proper is supported by the frame member 100. This construction permits detaching the machine from the cabinet struc-.

ture and placing it upon a table if desired, and for this purpose the U-frame 100 is p: ovided with a fiat base portion as shown best in Figs. 7 8 and 10. The detaching is easily accomplished by lifting rods 76 from the seats 79 and removing hinge pin 71. The machine may then be lifted .out of the cabinet by sliding roller 95 out of guide 96.

Ironing shoe and mounting Arm 102 extends for a short distance substantially verticallyand then divides into two branches 105 and 106. Branch 105 extends above branch 106 and carries on its top a narrow platform or feed table 107 which extends laterally the length of the ironing shoe and roll and extends forwardly to a point close to the top edge of the ironing shoe, there being a narrow space 109 between this edge and the shoe for the purpose of preventing conduction of heat from the shoe to the table. Table 107 is secured to arm 105 in a suitable manner as by cap screws 110.

To branch 106 of arm 102 is secured a shell 115, which shell is open at its outer side and in turn has secured to it the ironing shoe 116. The latter is a rather thick piece of metal cylindrically concave on its outer surface as at 117 to conform to the shape of the roll with which it co-acts. The part 116 may be of :ast iron, or of other suitable metal, such as certain alloys. Shoe 116 is heat insulated from shell 115 as indicated at 118, but secured thereto as by screws 119,. and carries upon its under side electric resistance heating elements 120, these being indicated as pressed tightly against the shoe by a yoke member 121 and bolt orscrew 122. The wires from said elements 120 pass out of a suitable opening 123 in shell 115 into the hollow arm 102, one of said wires leading to a conventional switch 125 having handle 126 and set in the wall-of arm 102, the other wire leading to a junction box 125a;

Although the ironing shoe 116 is heat insulated from the shell 115, the latter is likely reaching under the end thereof to arrange the work or for any other reason, is apt to touch the shell 115 with his. arm or hand. There is, therefore, provided at each end of the shell an arm guard 130 (shown best'in Figs. 7 and 10). This guard consists of a heat insulating pad secured to shell 115 by means of a cover and screws 131.

Wiring The wiring diagram for the machine is shown in Fig. 30. In this figure the junction box 125a is indicated by the two bus bars 125?) and 1250, these being connected to the two wires of cord 125d leading from a suitable source of current. v

From bar .125?) there is a lead to one end of one of the heater elements 120 and then to the other in series and to one pole of the switch 125. A second lead from bar 125?) connects with the same pole of switch 125 through lamp 127. As the other pole of switch 125 connects to bar 1250, closing switch 125 will energize both of these circuits so that the lamp will indicate when the heater current is on and act as a telltale therefor.

Roll driving mechanism As mentioned above, the roll numbered 150 is supported on arm 103 of frame member 100. This portion of the frame *member 100 furnishes a housing-for the roll operating mechanism and to it is also secured a motor 151 for driving the operating mechanism.

In Fig. 11, a portion only of the motor casing is shown at 150 with the motor shaft 151 projecting into the housing 152 for the reduction gearing indicated as a whole by 153. This reduction gearing 153 is spur gearing and in the specific embodiment shown, re-

duces the motor speed of 1000 to a roll speed of 1. The motor and power take-off shafts are shown at 151 and 154 respectively in Figs. 10 and 11.

The reduction gearing 153 differs from the is included for breaking the continuity of a possible electric circuit therethrough. This means comprises means for insulating housing 152 froni the motor housing 150 by means of a fibre gasket 152a so arranged as to form an oil-tight and insulating joint. The details of this joint are shown more clearly in Figs. 31 and 32.

In these figures, the motor casing 150 is secured to the end wall 152d in any suitable fashion and the latter is secured to housing 152 by means of screws 310 passing through. 5 end wall 152d and into lugs 311 inside of 15 Further, any possible circuits through the reduction gearing are prevented by means of a fibre gear interposed in the series as shown in Figs. 33 and 34.

In these flgures,the shaft 151 is from the motor, and gears a, b, c, d and e are carried by the end wall 152d of the housing. The remaining gears are carried by the end wall155 of the housing. The next gear in the series, after the gear e,'is a fibre 'gearconstructed as indicated in Fig. 34. In this figure, a fibre gear 315 carries a small pinion 316 which has a projecting lateral sleeve secured in gear 315 in any suitable manner and both are carried on stud 317. The end of the stud 317 and of surface 319 of the gear as indicated.

Further, as shown in Fig. 33, gear 315 will' mgs 181 and 182 for the ends thereof,-the roll be somewhat widerthan the other gears.

In using the fibre gear 315 as described, it should be noted (see Fig. 33) that, because of the width of gear 315 co-acti-ng with pinion e, which is narrower, there is a space between pinion a and gear 7 which overlaps it, the gear series being from pinion 6 through 315 and 316 to gear Further, the small airgap shown in Fig: 34 at the end of shaft 317 causes a spacing at this point The gear train a, b, o, d, e is by these two gaps effectively insulated from gear train 7, g, h, the latter being pinned to the power take-off shaft 154.

Further, it should be noted that the reduction gearing. 153 is spaced from the walls of housing 152 by the inwardly projecting bosses 1526 and 1520, which bosses are sulficiently long so that they extend above the oil level when the machine is turned on either end, the horizontal oil level beingabout as shown in Fig. 11. This prevents leakage of oil out of the housing 152 when the machine is in folded position. 4

Shaft 154 projects through wall 155 of the housing 152 into a chamber directly at the base of arm. 103 and carries looselymounted thereon a sleeve 160,- which has keyed or otherwise secured to it a sprocket wheel 161. At one end of sleeve 160 is a flange 162 acting as athrustmember by means of which the sleeve maybe moved longitudinally of the shaft 154, and at the other end there is a flange 163 notched at its edges to form one the bushing 318 in gear 315 will be below the eas es member of a dog clutch, the other member of the clutch being formed on gear 164 which is pinned or otherwise fixed to shaft 154. The sleeve 160 is spring-pressed toward clutch engagement by means of a spring 165 acting against wall 155 and flange 162.

Co-acting with sprocket 161 is a chain 166 which leads up within arm 103 to another sprocket 167 as shown in Figs. 8 and 12. The latter sprocket 167 is mounted upon a shaft 168 by means of which the drive is transferred to the end of roll 150. Shaft 168 carries another sprocket 169 which through chain 170 drives sprocket 171 secured to the I end of roll 150, as shown in Fig. 12.

Roll supporting mechahism As is desirable 'in ironing machines, the

roll 150 has two distinct movements, viz., rotary and the movement toward and away from the ironlng shoe 116. The rotation of p the roll has been described under the caption roll driving mechanism and the supporting mechanism, allowing oscillation, will now be described as the roll supporting mechanism.

It will be noted, particularly from-Figs. 7 to 12, that roll 150 is mounted upon arm 103 of frame 100, located centrally of theroll and that this mounting is by means of a yokeindicated as a whole in Fig. 12 by numeral l80which spans theroll and furnishes bearbeing supported in said bearings by shaft portions 183 and 184 extending outwardly from the spiders or disks 185 and 186 forming the roll ends. Shaft 183 is merely a short piece keyed or pinned in disk 185 by pin187, but shaft 184, while secured in the same manner, i. e., by pin 188 to disk 186, extends through bearing 182 and has its free end of hexagon 6r other suitable shape as shown at 189 in Figs. 10 and 12. This hexagon shaped end .fits into and makesa driving connection with sprocket 171. The same sort of driving connection is used with sprocket 169 and shaft 168, both sprockets being prevented from coming 011' the shafts by means of the cover The horizontal tubular member mentioned.

is made of two short tubes 197 and 198 keyed into the ends of a connecting piece or journal knuckle 200 by means of keys l93a and 19411 which is directly supported inthe bearings iii Leeasea to a block 203 fitting movably in the inner end of tube 198. This lock 198 furnishes an anchorage for one end of aspring 204, illusthe last being functionally an integral part of yoke 180, which is thus actuated as a whole.

The adjustment of spring block 207 is shown most clearly in Fig. 13. In this figure, tube 198 is shown askeyed to arm 192, with block 207 therein. The latter is shown as provided with a peripheral worm pinion portion 208, adapted to'co-act with a. worm 209 carried in arm 192. v

Tube 197 carries in its ends the two blocks 210, forming bearings for shaft 168.

The connections and operation of arm 201 with the spring-204 are shown in the enlarged detail views in Figs. 14, 15 and 16, the latter two being sections on line 1515 ofFig. 14, while Fig. 14 is an enlargement of a part of Fig. 12 with certain parts omitted.

As may be seen from these figures, when arm 201 is moved to the right and the roll 150 thereby lowered against the-ironing shoe 116, there is permitted asmall amount of relative movement between the member 200, connecting tubes 197 and 198, and the head portion of arm 201, which as already stated fits under the semi-cylindrical part of member 200: V

In order to prevent too much relative movement, the edges 200a and 2006 are adapted to abut shoulders 201a and 2016 formed on the head portion of arm 201. In making the assembly, the spring 204 is so adjusted that the parts 200a and 201a come together when the roll is raised and suflicient tension is added to produce a pressure of about 100 pounds between the roll and shoe when the former is lowered. lln lowered position of the roll the parts 200a and 201a are separated by a small distance so that the required iron-,

ing pressure may be on the thinnest materials constituting the work.

Further, as a torsion spring under these conditions has substantially a straight line stress curve, the pressure on the work is substantially the same regardless of thethickness, until the parts 2006 and 2016 come together. But, as a small movement at the radial distance of shoulder 2016 from the center of movement corresponds to a much larger movement by the roll, the limit of thickness of workis beyond that which it is practicable to operate upon.

Roll actuating mechanism Under this caption will be'described the means for moving the arm 201 for the raising and lowering of the roll 150 and reference is made chiefly to Figs. 11 and 17 to 27 inclusive.

As mentioned in connection with the roll driving mechanism, shaft 154, leading from the reducing gearing, has secured upon it a gear 164, and this gear forms one member of a dog clutch, the other member being a toothed flange 163 on sleeve 160. The gear 164 has one face machined away leaving the teeth 1640; projecting from the side as indicated in Figs. 18, 19 and 20, so that the teeth 163a of flange 163 fitin between the projecting portions, thus forming a positive drive for the sleeve 160.

When the sleeve 160 is in the position shown inFig. 11, the clutch 163164 is engaged and consequently the sprocket 161 is driving the roll 150 through the connections already described and at the same time gear 164 is driving a gear 215 which forms part of a sleeve 216, having at its other end a flange 217, which sleeve is loosely carried on a shaft 218, mounted in bearings 219 in the drive housing.

Through the agency of a clutch, indicated as a whole by numeral 240, the sleeve 216 and gear 215 will rotate shaft 218 which carries at one end a crank arm 220 adapted to operate a pitman composed of links 221 and 222 connected to thebottom end of arm 201. description of Figs. 8 and 9 for explanation of pitman construction.) Thus, when clutch 240 operates to connect sleeve 216 to shaft 218, the arm 201 is moved and consequently the roll 150 will be moved up or down.

When the roll 150 is raised, the arm 201 will, of course, be in the position shown in dotted lines in Figs. 8, 17 and 18, and, in this po'sition, the clutch members 163 and 164 will be out of engagement, as inFig. 20. This disengagement is accomplished by a hook 226 secured to arm 201 acting on a flange or step 226 on the throw-out lever 227. This lever 227 is hinged to the housing as at 228 and has a part 229 operating on flange 162 of sleeve 160 so that when the arm 201 is moved to the left (see Fig. 17) hook 225 acting on lever 227 causes the sleeve 160 to move toward the right (Fig. 18) thus disengaging clutch 163-164 and at the same time compressing spring 165. Correspondingly, when the arm 201 moves to the right (Fig. 17) the reverse action takes (See place and the clutch 163-164 is engaged so that the roll 156 is driven.

For a purpose to be described later, lever 227 may be held in its clutch disengaging posn tion by means of a hand operated cam piece 230 hinged in the housing at 231. W hen this piece 236 is in the dotted line position as shown in Fig. 18, the arm 201 may operate repeatedly without rotation of roll 150.

As so far described, when the motor is operating, and clutch 246 enga ed, the roll 150 would be oscillated up and own repeatedly would start and stop rotation with each oscillation.

The clutch then automatically releases and the shalt is positively stopped and held until such time as the oper ator sees fit to operate the roll again.

@lutch 246 consistso'l the driving flange or notched clutch disc 217 on sleeve 216 and the driven member or clutch body 241 which is liked to shalt 218 as by pin 242. Clutch body 241 carries in suitable slots two slid ing keys 243 adapted to slide laterally oi" the body and engage slots, 217a in disc 217 each key 243 being spring-pressed toward engagement by means of a spring 244 located in a seat beneath the key slot, which spring operates on a plunger 245 connected to the key 243 by suitable means such as the pin 246.

Each of the keys 243 is provided with a base portion 243a, which carries at one end a deeper rectangular engaging portion 243?; and at its other end a deeper portion 2430 part.

It will be noted that body 241 has a part of the same diameter as disc 217, with a smaller diameter portion 241a, around which is a ring 247 which will be called the cam ring. This ring is wider in its upper halt'tha-n in the keys 243 between the ends thereot. The wider portion of ring 247 is stepped down to the narrower portion abruptly on one side as at 247 a and slopes down on. the other side as at 2475 forming a cam surface. 1 a

Also, partly surrounding part 241a of. the body 241 is a cam member 248 which consists of a disc, flanged about a portion of its periphery as at 248a, the ends of the flange e ing cam surfaces as at 2485. Member 248 is also provided with a lateral tongue 249 adapted to lie in a groove 250 in bearing member 219 in order to prevent its rotation.

Cam ring 247 is provided upon its upper *side with a post 255 to which is connected 9. spring 256, antlhored at its other end to the housing, in such fashion as to tend to draw Lseaeee a lever 260 secured as at 261 to a vertical shaft 261a supportedin bearing 261?) and having secured to its other end an arm 2610 to which is secured link 262 and spring 263, the link being connected to a hand lever 264 projecting from the front of the machine (see Figs. 2, 26 and Lever 260, at the clutch end thereof, is roughly @-shaped, as shown in Fig. 26, and the post 255 is embraced thereby. Inside of said @-shaped end there is a shoulder 261a against which post 255 normally rests, and, when this is the case, the parts are as in 22, that is, sliding key 243 has its operating part 2430 held out of engagement with disc 217 by the corner 247a of ring 247. Further, one of two stops 265 provided on body 241 (see Fig. 21) is held by the overhang 263 of the C and the body thus prevented tr-om being'dragged around by the disc 217. v

'W hen the lever 264 is operated consequently lever 260 moved to the position indicated by the dotted lines in Fig. 26, the shoulder 2610i moves away from post 255 and the spring 256 immediately pulls the post (to the right in ldig. 23) into the bottom slot 266 of the Q and allows part 2430 or" key 243 to move to the left (Fig. 24) and consequently put the key in position to slide into one of the slots 217 a in disc 217 when it comes into registry, this sliding being caused by spring 244. At the same time, overhanging end 263 oil lever 260 is removed from the path of stop 265 allowing the body 241 to move with disc 217 as soon as the key 243 engages a slot 217a. lit for any reason the key 243 does not fully engage a slot 217a, as

'soon as the body 241, and therefore also the the latter allowed to resume the posit-ion shown in full lines in Fig. 26, in which position the overhang 263 acts with stop 265 to prevent further movement of body 241.

The two. keys 243 alternately function as just described and each is alternately idle.

Further, in order to prevent backward motion of the body 241 a second stop 267 is provided. This is the lower jaw of the C I and is wide enough so that it is always in active position, being made of a fiat spring piece under which the stops 265 may pass when the body 241 is moving in the right direction.

In operating machines in which the roll, or ironing shoe, as the case may be, israised or lowered by the motor used also for rotating the roll, it sometimes happens that the motor will stopwith work under theroll. For example, a fuse may burn out or some other mishap may occur to break the motor circuit. In such cases it is very important that means be present by which the roll may be lifted quickly without aid from the motor. Such a means is shown in the present embodiment in Figs. 8, 9 and 10.

'In Fig. 10 there-is shown a vertically placed rod 275 extending down into the housing for the actuating mechanism, guided by the guide lug 276, and retained in its upward position by spring 277. Figs. 8 and 9 show the lower end of rod 275 as resting on a lever 278 hinged to the housing as at 279. The free end of lever 278 rests on the extended portion of pin 222a which connects link 222 to pitman 221. Further, there is a spring 280 which extends between pin 222a and an anchoring lug 281 or the like on arm 201.

The action of this release is illustrated best in Fig. 9. In this figure with the parts in position as illustrated in full lines, the roll is down on the ironing shoe, and the pin 222?), which connects arm 201 to link 222, is below the line between pin 222a and pin 221a, which is the crank pin for crank 220, and held in this relation by spring 280. However, when the lever 27 8 is depressed and this relation changed to bring pin 222?; above the line, the roll spring 204: will cause the arm 201 to move forward until pin 2227) is in a position forward of pin 222m, whereupon the spring 280 will lift pin 222a so that the parts occupy the position illustrated in dotted lines in Fig.

9. In the latter position, the roll is somewhat above the normal lifted position and any workmay beremoved from the iron.

Upon again starting the motor, and operating clutch 240, the parts will automatically resume the relation shown in full lines in vFi 9.

- TVhen it is desired to use the machine for pressing, rotation of the roll is undesirable.

Therefore, means is provided for rendering clutch 163'164: inoperative to drive the roll. This means is the cam piece 230 in Figs. 17 and 18 acting as already described.

In the operation of ironing machines, it

sometimes happens that the operator, through forgetfulness or for some other reason, upon leaving the machine for a time, fails to turn ofi the heating circuit. If this happens when the roll is on the ironing shoe, the roll is apt to become injured through burning the padding and there is also the fire danger.

To provide against mishaps of this kind, there may be placed in the heater circulta thermostatic circuit breaker operating at a temperature a little above the proper ironing temperature. Such a device is indicated diagrammatically in Fig. 29.

\ In this figure there is indicated a bi-metallic bar 300 located preferably within shell 115 so as to be within the heating influence of the heater 120 or ironing shoe 116. This bar is anchored at 301 and its free end is adapted under, the influence of heat to slide the anchor post 302 in slotted guide 303 to the position indicated in dotted lines.

Adjacent the guide 303 as at 304: is pivoted a switch lever 305 adapted when in the full line position shown to bridge the contacts 306 and thus complete a circuit from lead 307 to lead 308. i

To lever 305 is connected a spring 309 secured at its other end to post 302.

Therefore, when the bar 300 under influence of heat assumes the position, or approximately so, indicated in dotted lines it will have moved post 302 beyond point 304 and the spring 309 will cause lever 305 to leave contacts 306 and assume the dotted line position, thusbreaking the circuit from lead 307 to lead 308 and the circuit will remain so until voluntarily re-set. Suitable stops 310 will be provided for the lever 305.

- From the foregoing description it will be seen ,that the present machine is one which, when in inoperative or folded position, is compacted into very small space, and is reasonably light in weight. Further, with a short roll open at both ends, its ironing capacity is greater than any machine with both ends of the roll closed and as great or greater than any having one end open, regardless of the length of roll used. And, by the use of the type of roll support and pressure spring, a substantially uniform pressure upon the work is obtained, regardless of the thickness.

Further, although the present description is specific to a single electric motor both for rotating and actuating the roll, it should be understood that where the term motor is used, it is intended to be construed in its broad sense of a prime mover, whether the operating medium be electricity, steam, hydraulic power, or other source of energy. It should also be understood that under some conditions it may be found desirable to use two motors, one for rotating the roll and one for actuating the movable element, i. e. opening and closing the space between the cooperating ironing elements, whether this be through moving one of the elements or the other, or both.

In the modified form of clutch shown in Figs. and 36, the element 248 is eliminated and in its place is used the spring member 325. Thismember consists of a spring yoke secured to a pin 326 adapted to be secured in a boss 327, formed in the housing below the bearing 219, by means of it set screw 328. This yoke has two arms 330 and 331 embracing a reduced portion of part 241a of the clutch body 241. Arm 330 has a cam-shouldered raised portion 332 which rides up on the end of a key 243 as shown in Fig. and when the shoulder 2am isremoved from behind the key portion 2430, the spring arm. 330 promptly pushes the key into a slot 2170a, In this form of clutch, keys 243 will be somewhat longer than in, the other form described, and it will not be necessary to use the parts 2% to 246. Further, the other arm 33]. will act as a stop against backward. movement of the clutch body by furnishing an abutment 333 on its end for the end of a key 2&3, so that the stop 26'? may also be omitted.

The bent tip 335 on arm 330 serves to prevent motion of the spring arm too far forward. This tip will rest against the end of clutch body 2 H.
